- Abstract
Introduction and objectives: Immunoglobulin A vasculitis (IgAV), the most common childhood vasculitis, is associated with gastrointestinal (GI) involvement in 50–75% of cases. The aim of this study was to describe the characteristics of GI involvement in a cohort of hospitalized children with IgAV. Methods: We retrospectively evaluated patients hospitalized for IgAV at Meyer Children's University Hospital, from January 2010 to December 2020. The children's families were interviewed by phone and asked about disease relapses. Results: In the study period, 118 children had GI involvement, corresponding to 75% of children hospitalized for IgAV. Their median age was 7 years (interquartile range 6–9). The most frequent GI manifestations were abdominal pain (96%), bleeding (71%, mostly occult), vomiting (58%), and diarrhea (17%). GI complications, observed in 18%, were intussusception (14%), appendicitis (3%), gallbladder hydrops (2%), and ileal perforation (1%). Abdomen ultrasound, performed in all cases, was abnormal in 68%. Abdomen X-ray, performed in 19 patients, showed pathologic findings in 84% of them. Selected children with severe manifestations also underwent abdomen computed tomography (2/118; 2%) and GI endoscopy (5/118; 4%). Steroids were used in 80 (67.8%) cases. The use of second- and third-line therapies was necessary in three cases. Relapses, investigated in 80 cases (68%), occurred in 21% of them. Key Points • The present retrospective study describes a cohort of 118 patients hospitalized for gastrointestinal (GI) involvement in immunoglobulin A vasculitis (IgAV) at a tertiary care children's hospital from January 2010 to December 2020. • The most frequent GI manifestations were abdominal pain (96%), vomiting (58%), and diarrhea (17%). GI bleeding was reported in 71% of children, and it was occult in most cases. • GI complications, occurring in 18% of cases, were intussusception (14%), appendicitis (3%), gallbladder hydrops (2%), and ileal perforation (1%). • Steroid treatment has been successfully used in severe GI manifestations; however, our data do not support its association with low relapse risk. Conclusions: The present study describes a large pediatric cohort of GI involvement in IgAV. Steroid treatment should be used when GI manifestations are severe. The association of steroid use with relapse risk is not currently established.
